If you're running a double glazing or windows installation business in the UK, you already know the pain: a customer calls, you visit the property, take measurements, then spend the next hour wrestling with a spreadsheet trying to get the quote right. Multiply that by 10 quotes a week and you've lost an entire working day — every single week — just on paperwork.
The Quoting Problem Every Glazing Business Faces
Ask any glazing business owner what takes up the most non-installation time in their week, and the answer is almost always the same: quoting. It's not just the time — it's the complexity.
A single double glazing quote might involve 6 windows of different sizes, 2 doors, multiple frame colour options, different glass specifications (double vs triple glazed, obscure glass for bathrooms, acoustic glass for road-facing rooms), hardware choices, and a composite front door with its own entirely separate pricing structure. Then you need to apply VAT, check your minimum price floors, apply any promotional discounts, and format it all into a professional document the customer will actually read.
Done manually in a spreadsheet, this takes 30–60 minutes per quote. Done with an AI quote builder built specifically for the glazing industry, it takes under 5 minutes — and the output is more accurate, more consistent, and more professional.
The Manual Quoting Trap
- A 10-quote week = 5–10 hours lost to spreadsheet work
- Different reps quote different prices for the same job
- Calculation errors erode margins without you noticing
- Slow turnaround means customers accept a competitor's quote first
- No version history — impossible to track what was quoted and when
The Real Cost of Manual Quoting
Let's put some numbers on this. The average glazing sales rep earns around £30,000–£40,000 per year in the UK — roughly £15–£20 per hour. If they're spending 45 minutes on every quote, and producing 10 quotes per week, that's 7.5 hours per week, or £112–£150 in labour cost — just for quoting.
Over a year, that's £5,800–£7,800 per sales rep spent on manual quote preparation. For a team of 3 sales reps, you're looking at up to £23,000 per year in quoting labour alone.
But the hidden cost is even bigger: speed to quote. Research consistently shows that the first company to send a quote wins the job more than 50% of the time. When your competitor can send a quote in 10 minutes and you take 2 days, you're losing jobs before the conversation even starts.

How an AI Quote Builder Actually Works
The term "AI quote builder" can sound intimidating, but the reality is elegantly simple. Here's exactly what happens when a glazing sales rep uses WinWaz's AI Quote Builder on a customer visit:
Select the customer
The rep opens WinWaz on their phone or tablet, selects the customer from the CRM (or creates a new one in 30 seconds), and starts a new quote.
Add products and enter dimensions
The rep selects the product type (e.g. "uPVC Casement Window") and enters the width and height in millimetres. The AI engine instantly calculates the area in m² and applies the correct area-based price.
Configure product options
The rep selects frame colour (e.g. Anthracite Grey +£85), glass type (e.g. Triple Glazed +£120), and hardware finish. Each option's price modifier is applied automatically — no manual calculation needed.
AI pricing suggestions
The AI engine analyses the quote and suggests optimal pricing based on job size, product mix, and historical win rates — helping the rep price competitively without underselling.
Review and send
The rep reviews the quote — VAT calculated, totals correct, professional layout — and sends it to the customer via email or WhatsApp QR code. The whole process takes under 5 minutes.
Time Savings: The Numbers Don't Lie
We surveyed glazing businesses using AI quote builders and the time savings are consistent and significant. Here's what a typical week looks like before and after:
Before: Manual Quoting
- 10 quotes × 45 min = 7.5 hours/week
- 2 pricing errors per week on average
- Quotes sent 1–2 days after site visit
- 3 hours/week chasing quote status
- No visibility on which quotes are open
After: AI Quote Builder
- 10 quotes × 5 min = 50 minutes/week
- Zero calculation errors
- Quotes sent same day, often on-site
- Automated follow-up reminders
- Full pipeline visibility in real time
The Compound Effect
Saving 6.5 hours per week on quoting doesn't just save money — it frees your sales reps to do more site visits, follow up on more leads, and close more jobs. A glazing business that can handle 30 quotes per week instead of 10 has the potential to triple its revenue without hiring additional staff.
Accuracy & Consistency: No More Pricing Errors
Time savings are important, but for many glazing business owners, pricing accuracy is the bigger win. Manual quoting errors are surprisingly common — and surprisingly costly.
A typical pricing error might look like this: a sales rep forgets to apply the Anthracite Grey frame colour surcharge (£85 per window × 8 windows = £680 missed), or miscalculates the area of an unusually shaped window, or applies last year's pricing to a product that's had a supplier price increase. These errors either erode your margins silently or, worse, get spotted by the customer and damage trust.
An AI quote builder eliminates these errors entirely. The pricing rules are configured once by the business owner — base prices, option modifiers, minimum price floors, VAT rates — and then applied consistently to every single quote, by every sales rep, every time. There's no human error in the calculation layer.
Consistent Pricing
Every rep quotes the same price for the same job. No more undercutting each other or inconsistent customer experiences.
Margin Protection
Minimum price floors prevent quotes going below your cost threshold — protecting margins automatically.

Every quote version is saved. See exactly what was quoted, when, and by whom — invaluable for disputes and analysis.
Sending Quotes Instantly via WhatsApp
One of the most underrated features of a modern AI quote builder is WhatsApp QR sharing. In the UK glazing industry, WhatsApp is how customers communicate — it's faster than email, more personal, and has a 98% open rate compared to email's 20%.
WinWaz's AI Quote Builder generates a WhatsApp QR code for every quote. The sales rep shows the QR code to the customer on their phone screen — the customer scans it with their own phone, and the quote link opens instantly in WhatsApp, pre-loaded with a professional message. No email address needed, no waiting for the customer to check their inbox.
This is a game-changer for on-site sales. The rep can generate the quote while still at the customer's property, share it via WhatsApp before leaving, and follow up the same evening. The customer has the quote in their hands within minutes of the site visit — dramatically increasing the chance of a same-day or next-day decision.
WhatsApp QR Sharing
Generate a QR code for any quote. Customer scans it on-site. Quote opens in WhatsApp instantly — no email, no waiting, no friction.

"Before WinWaz, I was spending Sunday evenings doing quotes for the week ahead. Now I do them on-site in 5 minutes and send them before I've even left the customer's driveway. I've won 3 jobs this month just because I was the first to send a quote."
